Abstract: The disclosure relates to solar cell, and especially to a method for manufacturing a crystalline silicon solar cell module. The method includes: a) providing a solar cell module to be laminated, including a back plate, a first bonding layer, a crystalline silicon solar cell component, a second bonding layer and a top plate in contact in sequence, where the crystalline silicon solar cell component is a crystalline silicon solar cell or a cell string formed by connecting multiple crystalline silicon solar cells; b) laminating the solar cell module to be laminated under current injection, to obtain a laminated solar cell module; and c) installing a frame and a junction box on the laminated solar cell module, to obtain a crystalline silicon solar cell module. The crystalline silicon solar cell module is under the current injection during the laminating process, improving the performance against light-induced degradation.
